Teoretyczne i praktyczne aspekty systematyki procesów erozji wodnej gleb

The paper outlines problems concerning semantics of the notion of soil erosion, range of constituent processes; the review analysis of existing systems of the classifi cation of these phenomena has been presented. The author also proposed multicriterial systematics of water soil erosion processes – uniting onomastics from the range of earth’s sciences with the nomenclature applied in agricultural sciences, taking into consideration meritoric and practical aspects. The systematics bases on the general criteria (main causative factor, and type of process) and 6 itemical criteria (a–f): component processes, character of degradation, object of infl uence, way of infl uence, effects and preventive measures. Basing on these assumptions the systematics of three essential types of water erosion (surface, ravine and underground) has been presented. The multicriterial analysis of processes, considering also preventive measures to soil erosion degradation of mechanical, chemical and hydrological type, as well as of accumulative type (the so called harmful sedimentation) will help to recognize the complicated structure of these processes.
